When you make one of the world's finest"driver's cars," how do you top it? You give it all everything if you are Porsche. This is the case the ultimate expression of the GT3 lineup of street/track firearms of Porsche, with this 911 GT3RS. In RS specification, displacement of the normally aspirated flat six increases from 3.8 to 4.0 liters, producing 500 horsepower. Insert 918-derived seats, a magnesium roof and a roll cage that is standard-equipment, and you also own a car that can turn a 7:20 lap of this Nordschliefe from the showroom floor. AUTOart's 1:18-scale ABS composite copy of the Porsche 911 GT3RS catches the visceral appeal of the thing in detail. It features rendered front and rear fender vents that help set the RS apart from its GT3 brethren, as well as beautifully implemented interior trim and road wheels.
